INTERCHANGEABLE CARRIAGE FOR TYPE-WRITERS.

SPECIFICATION forming part of Letters Patent No. 793,069, dated June 27,1905.

Application filed August 18, 1902. Serial No. 120,157.

To (1, 11:71.07), 7'2. max/ concern:

Be it known that we, JOHN J AY Hnnmns, residing at 210 lVestFourthstreet, New York, county of New York, and Ax'rnoxv A. HIE- BER, residingat 12%3 Putnam avenue, Brooklyn, county of Kings, State of New York,citi- Zens of the United States, have invented certain new and usefulImprovements in Interchangeable Carriages for Type-"riters, fullydescribed and represented in the following specification andtheaccompanying drawings, fori'ning a part of the same.

The object of the present invention is to furnish a type-writingapparatus adapted not only to write upon an ordinary rotary platen, butalso to write upon theleaves of books or other sheets of paper held upona stationary flat platen. This object is accomplished by providing'twobeds, one having a flat platen adapted to hold the paper stationary andto support the type mechanism movably and the other adapted to supportthe paper movably and to hold the type mechanism stationary, and alsoproviding a type mechanism having a baseframe which is fittedinterchangeably to similar supports upon the two beds, so that it may beused interchangeably with either. "here the bed has a stationary fiatplaten, it is suited to support the leaf of a book as in other booktype-writing machines, andit may also be used for writing upon flatsheets of paper larger than those which can be conveniently held by arotary platen, and the letterspacing is secured by the bodily movementsof the type mechanism, while the line-spacing is effected by a carriagesupporting the same. lYhen the type mechanism is fitted to such bed, thepaper is held stationary, as in similar type-writing machines, and thetype mechanism moves beneath the lingers of the operator, and theposition of the hands must be constantly changed to operate upon the imoving keys; but the interchangeability of l the type mechanism with theother bed and its platen enables the type mechanism to be heldstationary when not writing in books and avoids such a requirement ofthe operator. Upon the other bed the type mechanism is held stationaryover a movable carriage, and the movement of the keys is avoided, andthe movable carriage, with its rotary feeding device, furnishes themeans of moving the paper for line and letter spacing under the typemechanism. The type mechanism may be of any well-known or suitablecharacter, and the means of holding itinterchangeably upon the two bedsmay be varied at pleasure, as the essential feature of the invention isatype-writing mechanism having one platen adapted to hold the paperstationary and having supports to hold the type mechanism movably, whilethe other bed has a platen adapted to hold the paper movably and hassupports to hold the type mechanism stationary.

in the drawings illustrating the invention a type mechanism is shown ofthe class claimed in our application, Serial No. $5,810, filed February4, 1901, in which the type-bars are arranged to strike downwardlythrough an open-bottom frame; but the type-bars and the means foroperating them are omitted in the drawings, as they form no part of thepresent invention and would obscure the representation of the partswhich are essential.

Figure 1 is a plan of a bed having a papersupporting carriage and platenmovable upon tracks in the lower part and having above such carriageelevated supports to receive the base-frame of the type mechanism andhold it stationary. Fig. 2 is a front view of the same; Fig. 3, a rearview of the same; and Fig. 4:, a front elevation of thepaper-carriageand platen, upona larger scale, detached from the bed. Fig. 5 is across-section of the same, the section being adjacent to the letters Aa) '11 at the left-hand end of Fig. l, with one of the boxes for thehinge-rail broken off to expose the guide-rolls which embrace such rail,and such box is shownseparately in Fig. 6. Fig. 7 is an edge view of thebed combined with a stationary platen for use in a book typewriter, thebase-frame of the type mechanism being shown thereon; and Fig. 8 showsan end view of such base-frame detached from both of the beds. Fig. 8shows the inner side of one of the boxes for the hinge-rail with thecollar (Z having the tooth *0. Fig. 9 is a plan of the bed shown in Fig.7, with a longitudinally movable carriage having a guide-rail. and atrack-rail thereon. with the base-frame of the type mechanism fittedthereto. Figs-1O to 12 show an alternative construction.

a designates the base-frame of the type mechanism, having at the rearedge two posts 6, Fig. 2, carrying grooved guide-rolls c, which arefitted to a cylindrical rail (Z, which serves as a hinge-rail forturning the type mechanism upwardly to inspect the printing. In Fig. 5dotted lines are extended upwardly from the base-frame a to indicate thearrangement of the type-bars 2f, the keys t, and the space-bar t Topermit such upturning of the type mechanism, the hinge-rail may be heldstationary and the grooved faces of the rolls slipped thereon or therolls may be gripped firmly upon the hinge-rail and the ends of suchrail journaled to turn as an axle. The latter construction isshown inthe drawings, in which Figs. 1 to 5 show the base-frame of the typemechanism held stationary upon a bed having side bars A and cross-barsB. The upper parts of the bars A are provided with lugs a, which supportthe base-frame, and track-rails 2' are affixed to the lower part of theside bars A to support rollers it upon a paper-carriage g, which carriesa 'rotary platen g movably beneath the type mechanism. The rear side ofthe carriage g is provided at opposite ends with boxes e to support thehinge-rail (Z. The rail is formed, as shown in Fig. 1, with collars (Znear each end to fit inside the boxes and prevent longitudinal movement;but the rail is detachable from the boxes, so that it may be removedfrom the bed, with the type mechanism, for use upon another bed, asdescribed above. The hingerail is provided with teeth 1' to serve as arack-bar, and the usual feed-pinion k and escapement-wheel Z are shownin Fig. 1, supported upon the base-frame a, so that when actuated in theusual manner by the keys of the type mechanism they cause the hinge-railand the paper-carriage g (to which it is attached by the boxes 6) tomove step by step beneath the type mechanism for letterspacing. Theusual spring-drum m is shown in Fig. 1 attached to the bed A andconnected by band at with the end of the carriage 9, so as to move it inthe usual manner at each actuation of the spacing mechanism. Thespring-drum is not shown in Fig. 5 for want of room upon the drawing,but is fully shown in Fig. 1. The carriage g is shown in Fig. l

with guide-rolls 0 at opposite sides of the rotary platen g and in Fig.5 with small rolls 0 pressed upon the tops of the guide-rolls by springs0 A knob 29 is connected with the guide-rolls 0 by gears 21. and thepaper is fed across the surface of the platen step by step forline-spacing by turning the knob after writing each line. The side barsA of the bed are shown formed in Figs. 2, 3, and 5 with longitudinalslots A, through which a sheet of paper P can be inserted between therolls 0 and 0 and shifted intermittingly for line-spacing, while theletter-spacing in the lines is effected by the usual movement of thecarriage beneath the type mechanism upon the rails The base-frame a isshown provided upon the front edge with track-rolls q for use with astationary carriage, and such rolls are utilized with the bed shown inFig. 5 to hold the type mechanism stationary by their engagement withnotches q in the side bar A, as shown in Figs. 2 and 5. With the typemechanism held stationary the hingerail (Z, which is attached to thecarriage, moves longitudinally between the guide-rolls 0 when fed forletter-spacing; but such hinge-rail is so supported by the carriage 9that the baseframe a and the type mechanism supported thereby may beturned around the axis of the rail (Z whenever desired to inspect theprinting upon the paper beneath. During this operation the track-rolls(1 upon the base-frame are lifted from the notches q in the side bar Aand are afterward replaced in such notches, which restores the typemechanism exactly to its former relation with the paper.

The apparatus thus far described holds the type mechanism stationary, sothat the keys always retain the same positions under the fingers of theoperator.

Figs. 7 and 9 show the base-frame of the type mechanism transferred to aline-spacing carriage having sides 0" and ends 7, fitted to a bed whichis formed with sides .9 and end 8, adapted to rest upon a flatrectangular platen 3 to clamp thereon the leaf of a book or sheet ofpaper 5 which is to be inscribed. sheet is shown in Fig. 9 with a fewwords written thereon beneath the center of the baseframe a. The rearcorners of the spacingcarriage 1' are provided with boxes 6, the same asthose upon the paper carriage g (shown in the preceding figures) andarranged at the same distance apart as those upon the paper-carriage 9,so that the same or a simi-- lar hinge-rail (Z may be fitted thereto andsup- Such a I ITO port the rear edge of the base-frame a while its frontedge is supported by the track-rolls q, resting upon the front edge r ofthe spacing-carriage, as shown in Figs. 7 and 9. A spring-drum m isshown upon one end of the spacing-carriage, and a hook n is shown uponthe base-frame to engage the band n extended therefrom, so that thebase-frame may be moved over the paper upon the platen s forletter-spacingwhen the escapement-wheel Z is operated by the keys. Theright side 8 of the bed is shown provided with teeth, and a pinion or isshown journaled upon the spacingcarriage r and fitted thereto, whichpinion would be actuated in the usual manner to shift the carriage uponthe bed at suitable intervals for line-spacing. WVith this construc tionthe line-spacing is effected by the movement of the spacing-carriage 1',and the letter-spacing is effected by the movement of the type mechanismupon such spacing-carriage, the base-frame [Z of the type mechanismbeing supported by the rails r and (Z, with the latter of which it maybe turned up, as described above, to inspect the writing when desired.

The hinge-rail (Z is turned with the type mechanism by the engagement ofthe rackbar j with notches Zr (see Figs. 5 and 8) in the posts L, whichcarry the guide-rolls 0, and the type mechanism may thus be held in anoperative position or raised to inspect the printing by stops applied tothe hingerail (Z, and such a stop is shown in Fig. 8 for supporting thecarriage to make any desired correction in the printing. When thecarriage is turned upward to a position of equilibrium above thehinge-rail (Z, it is held in such position while inspecting the printingbya tooth '0 upon one of the collars (Z', which are rigidly fixed uponthe shaft or hinge-rod (Z. The tooth e in such position engages a pin 1"upon one of the boxes 0. (See Fig. 8.) The construction of the boxes 6is immaterial, as their essential function is that of a support for theguide-rail (Z. If a single hinge-rail be used in permanent connectionwith the guide-rolls 0, such rail must be connected detachably with thesupports upon the two beds, so as to fit interchangeably upon both; butit is immaterial whether a single hinge-rail be used or correspondingguide-rails be provided upon the two beds and theguide-rollscconstructed to embrace them detachably.

in Figs. 1 to 9, inclusive, the hinge-rail (Z is shown removable fromthe boxes 6, each of the boxes having, as shown in Figs. 6 and 7, ahinged cap 6', pivoted upon the bearing a and provided with a latch e tolock it when secured over the bearing. WVhen unlatched, such removablecap may be thrown backwardly and the hinge-rail lifted from the bearing.If a single guide-rail be used in permanent connection with theguide-rolls c, as shown in Figs. 1 to 9, the hinge-rail must necessarilybe connected in a detachable manner with the supports upon the two beds,so as to fit interchangeably upon both; but it is immaterial whether asingle hinge-rail be used or corresponding guide-rails be provided uponthe two beds and the guide-rolls 0 constructed to embrace themdetaehably. Figs. 10 to 12, inclusive, show the latter construction, inwhich the guide-rolls 0 are separable, so that they may be detached fromthe hingerail and the type mechanism thus be used with either thestationary or the movable sheet of paper.

Fig. 10 shows in plan a bed A adapted to serve the same purpose as thestationary bed A B shown in Fig. 1, but having no front support for thebase-frame a of the type mechanism, as the latter is designed to restupon the moving carriage g. The bed A has rails Z to support the movingcarriage. Posts 1 are shown projected upwardly from the rear edge of thebase-frame a and the upper guideroll 0 pivoted thereon, while the lowerguideroll is pivoted upon a stud 2 upon a block 3, which is movablevertically in a slot 4 in the base of the post. Levers 5 are hinged uponthe posts 1 over the blocks 3, and each is formed in its lower end withan eccentric slot 6, fitted to the stud 2 in one of the boxes. Thelevers 5 are connected by a link 7, and one of them is provided with ahandle by which both can be shifted at pleasure, the eccentric slotsoperating to raise and lower the blocks and the lower guide-rolls 0 whenthe lovers are moved back and forth. \Vhen the rolls (2 are separated bya suitable movement of the levers, as shown in Fig. 12, the baseframeand the type mechanism attached thereto can be removed from thehinge-rail (Z of one bed and transferred to the hinge-rail of anotherbed and the rolls engaged with such latter hinge-rail by reversing theposition of the levers 5 to press the rolls together, as shown in Fig.11.

Figs. 10 and 11 show ears 8 attached to the hinge-rail (Z in suitablepositions to admit the upper guide-rolls c and to hold such rolls fromlongitudinal movement upon the rail. The ears 8 serve to hold the typemechanism stationary over the longitudinal moving carriage g (which isshown in Fig. 12, but omitted from Figs. 10 and 11) the same as theengagement of the rolls (1 with the notches q, shown in the side bar Ain Figs. 2 and 5.

As stated above, no side bars like A are provided with the bed shown inFigs. 10 to 12, inclusive, as the base-frame a is supported wholly bythe hinge-rail (Z and the moving carriage g.

WVith the construction shown in Figs. 1 to 9 the'type mechanism may beused with the movable platen or the stationary platen, by opening theboxes 0 and removing the type mechanism, with the hinge-rail (Z, fromthe supports which are connected with one of the platens, and fitting itto the supports connected with the other platen. \Vith the constructionshown in Figs. 10 to 12, inclusive, the hinge-rails are securedpermanently in their supports, and the type mechanism is transferredfrom one platen to the other when required by separating the rolls 0, asdescribed, and detaching them from the hinge-rail of one bed andtransferring them to the hinge-rail of the other bed. The apparatus isthus adapted to write either in stationary books or upon sheets of paperfed movably beneath the type.

From the above description, it will be seen that the invention embracesa type-writing apparatus which comprises a platen adapted to hold thepaper stationary and having supports to hold the mechanism movably, andalso a platen adapted to hold the paper movably with supports to holdthe type mechanism stationary, and the type mechanism having means toengage the said supports interchangeably.
